Abstract

A surgical instrument is disclosed. Various embodiments include an elongated shaft that defines a central axis and has a distal end portion that is configured to operably support a circular staple cartridge therein. At least one detection member may be operably supported within the elongated shaft. Each detection member may have a distal portion that is radially deployable away from the central axis upon application of a deployment motion thereto. The distal end portions may have a bumper or light mounted thereto.

Claims

1. A surgical instrument comprising:

an elongated shaft defining a central axis and having a distal end portion configured to operably support a circular staple cartridge therein;

at least one detection member operably supported within said elongated shaft, each detection member having a distal portion that is radially deployable away from said central axis upon application of a deployment motion thereto; and

a light on said distal portion of said detection member.

2. The surgical instrument of claim 1 wherein each said detection member is movably supported in a detection and acquisition housing that is movably supported within said elongated shaft.

3. The surgical instrument of claim 1 wherein said distal portion of each said detection member naturally bends radially away from said central axis when said distal portion is axially advanced out of a distal end of said detection and acquisition housing.

4. The surgical instrument of claim 1 further comprising:

at least one acquisition member operably supported within said elongated shaft, each said acquisition member having a tissue-piercing distal portion that is radially deployable away from said central axis upon application of a deployment motion to said acquisition member; and

at least one flexible knife member movably supported in said elongated shaft, each said knife member having a distal cutting portion that is axially advanceable out of said distal end portion of said elongated shaft upon application of an axial actuation motion thereto, each said knife member being selectively rotatable about said central axis upon application of a rotary actuation motion thereto.

5. The surgical instrument of claim 4 further comprising a tissue piercing barb on said tissue-piercing distal portion of each said acquisition member.

6. The surgical instrument of claim 4 wherein each said knife member has a tissue-piercing point formed thereon.

7. The surgical instrument of claim 1 further comprising an annular cutting member that is supported by said distal end of said elongated shaft for selective axial travel relative thereto.

8. The surgical instrument of claim 7 wherein said annular cutting member is supported to receive axial firing motions from a firing member operably supported in said elongated shaft.

9. The surgical instrument of claim 1 wherein said at least one acquisition member comprises a plurality of acquisition members.

10. The surgical instrument of claim 1 wherein said at least one knife members comprises a plurality of knife members.

11. A surgical instrument comprising:

an elongated shaft defining a central axis and having a distal end portion configured to operably support a circular staple cartridge therein;

at least one detection member operably supported within said elongated shaft, each detection member having a distal portion that is radially deployable away from said central axis upon application of a deployment motion thereto; and

at least one acquisition member operably supported within said elongated shaft, each said acquisition member having a tissue-piercing distal portion that is radially deployable away from said central axis upon application of a deployment motion to said acquisition member.

12. The surgical instrument of claim 11 further comprising at least one flexible knife member movably supported in said elongated shaft, each said knife member having a distal cutting portion that is axially advanceable out of said distal end portion of said elongated shaft upon application of an axial actuation motion thereto, each said knife member being selectively rotatable about said central axis upon application of a rotary actuation motion thereto.

13. The surgical instrument of claim 11 wherein each said detection member has a blunted distal end portion.

14. The surgical instrument of claim 12 further comprising a light on said distal portion of said detection member.

15. A surgical instrument comprising:

an elongated shaft defining a central axis and having a distal end portion configured to operably support a circular staple cartridge therein;

at least one detection member operably supported within said elongated shaft, each detection member having a distal portion that is radially deployable away from said central axis upon application of a deployment motion thereto; and

at least one flexible knife member movably supported in said elongated shaft, each said knife member having a distal cutting portion that is axially advanceable out of said distal end portion of said elongated shaft upon application of an axial actuation motion thereto, each said knife member being selectively rotatable about said central axis upon application of a rotary actuation motion thereto.

16. The surgical instrument of claim 15 wherein each said detection member has a blunted distal end portion.

17. The surgical instrument of claim 15 further comprising a light on said distal portion of said detection member.

18. A surgical procedure for treating a tubular organ, said surgical procedure comprising:

inserting a circular stapler head of a surgical instrument into the tubular organ;

deploying at least one lighted detection member operably supported by the surgical instrument from a retracted position to a deployed position adjacent a wall of the tubular organ; and

observing light from the lighted detection member through the organ wall to assess the location of the circular stapler head within the tubular organ.

19. The surgical procedure of claim 18 wherein said deploying the at least one lighted detection member from a retracted position to a deployed position comprises radially advancing the lighted detection member into the organ wall to create observable deflections in the organ wall.

20. The surgical procedure of claim 18 further comprising:

retracting each lighted detection member into the retracted position;

puncturing through a proximal portion of the tubular organ with a plurality of tissue acquisition members of the surgical instrument;

positioning the punctured proximal portion of the tubular organ adjacent to the stapler head;

severing the punctured proximal portion of the tubular organ from a distal portion of the tubular organ;

inserting an anvil into the distal portion of the tubular organ such that a connection portion of the anvil protrudes proximally out of an open end of the distal portion of the tubular organ;

securing the distal portion of the tubular organ to the anvil;

coupling the connection portion of the anvil to the surgical instrument;

drawing the anvil proximally toward the stapler head such that another portion of the distal portion of the tubular organ and the punctured proximal portion of the tubular organ are adjacent to each other and captured between the anvil and the stapler head;

stapling the another portion and the punctured proximal portion together; and

cutting through the another portion and punctured proximal portion adjacent to the staples.
